Using the theory of planned behavior as a theoretical framework, the present study examined psychosocial predictors of exercise intentions and behavior among 124 men and women with spinal cord injury. Theory of planned behavior constructs were measured using an exercise–specific questionnaire for individuals with spinal cord injury. Exercise behavior was assessed using an adapted version of the Godin Leisure Time Exercise Questionnaire. Regression analyses indicated that the theory of planned behavior had limited utility in this population. Among individuals with tetrapelgia, perceived behavioral control was the only determinant of exercise intentions and behavior. Among people with paraplegia, none of the theory of planned behavior constructs predicted exercise intentions or behavior. These results have methodological and practical implications for future research and exercise interventions, respectively.
